A Dynamical Boundary for Anti-de Sitter Space
Chethan Krishnan, Avinash Raju, P. N. Bala Subramanian
We argue that a natural boundary condition for gravity in asymptotically AdS spaces is to hold the {\em renormalized} boundary stress tensor density fixed, instead of the boundary…
An Alternate Path Integral for Quantum Gravity
Chethan Krishnan, K. V. Pavan Kumar, Avinash Raju
We define a (semi-classical) path integral for gravity with Neumann boundary conditions in dimensions, and show how to relate this new partition function to the usual picture o…
A Neumann Boundary Term for Gravity
Chethan Krishnan, Avinash Raju
The Gibbons-Hawking-York (GHY) boundary term makes the Dirichlet problem for gravity well defined, but no such general term seems to be known for Neumann boundary conditions. In th…
